[turba] problem with new install

[jason@monsterjam.org]

Im installing horde/imp/turba on my gentoo server and have horde and imp configured and working 
fine, trying to get turba working
I have emerged the version 2.1 and configured it through the webpage and saved it.. when I go 
to
http://10.1.1.2/horde/turba/

I get the following error..
Warning: require(/var/www/localhost/htdocs/horde/turba/) [function.require]: failed to open 
stream: Success in /var/www/localhost/htdocs/horde/turba/index.php on line 28

Fatal error: require() [function.require]: Failed opening required 
'/var/www/localhost/htdocs/horde/turba/' 
(include_path='/var/www/localhost/htdocs/horde/lib:.:/usr/share/php5:/usr/share/php') in 
/var/www/localhost/htdocs/horde/turba/index.php on line 28

which ive googled and scanned my logs but cant figger out what the heck is wrong..
anyone have a clue?

ooh, I also emerged 2.1.2 or turba and got the same problem, my config for tuba is as follows

beast config # cat conf.php
<?php
/* CONFIG START. DO NOT CHANGE ANYTHING IN OR AFTER THIS LINE. */
// $Horde: turba/config/conf.xml,v 1.6.2.3 2006/05/09 15:58:10 jan Exp $
$conf['menu']['import_export'] = true;
$conf['menu']['apps'] = array();
$conf['client']['addressbook'] = 'localsql';
$conf['comments']['allow'] = true;
$conf['documents']['params']['driverconfig'] = 'horde';
$conf['documents']['type'] = 'sql';
/* CONFIG END. DO NOT CHANGE ANYTHING IN OR BEFORE THIS LINE. */
beast config #

ooh, and I did import a previous version of my horde/imp/turba mysql database from my old 
freebsd server.. cant remember what version(s).
